IMPROVED HINGE AND FASTENER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, NATHANIEL B. SPOONEP., oi' Plymouth, in the county of Plymouth, and State of Massachusetts, have invented a new improvement in Blind-Hinges and Fasteners combined; and I do herebydeelare that the following is a. full, clear, and exact description thereof, which will enable. others skilled in the art .to

`make and use the same, reference being had tothe accompanying drawings, forming a part ot this specification, in whichp Figure 1 is an outside view of a window, with one shutter open and the other closed, fastened by my improved device.

' Figure 2 is a. horizontal section of the same, taken in the plane of the line a: as, fig. I.

Figure 3 is an enlarged detached side view of a single hinge, partly in section. `.Figure 4 is a top view of the lower part of the hinge.

Similar letters of reference indicate like parts. i

This'invention relates Vto a new and improved device for hanging window-blinds or shutters, by which they are fastened, when either opened or closed, automatically. It is simple and cheap.

A is the frame of a window, and B B the outside blinds or shutters, which are hung on the sides of the frame by hinges U C on each, as shown in gs. 1 and 3. The hinges are made in two parts, of malleable iron or other suitable metal, the upper part being secured to the inner edge of the blinds, and the lower part to the frame, with screws, as usual. The upper part ofthe hinge has a lat plate or disk, a, projecting at right angles from the blind, with a pin or pintle, b, onthe lower side, and the lower part of the hinge has a corresponding disk, c, projecting from the window-frame, with a socket, d, on the lower side, for receiving the pintle b. 'lhc pintle on the two upper hinges has a small catch-pin, e, run lthrough its lower end, just below the socket d, allowing the upper part of the hinge to be raised, and the disks a and c to be separated a little way only.

.The pintle on the two lower hinges is provided with a spiral spring, 7L, which passes down 'with it into the socket d, and is supported at its lower end upon a shoulder at the bottom of the socket, as shown in iig. 3.

The disk a,`on the lower hinges, is also provided with a small pin, z', on the lowerl side, and the disk c under it has three or more holes t" in it, for receiving the pin z3; and thus fastegning and holding the shutter in place when open or closed, or at any intermediate point that may be desired, for which the holes may be arranged, as shown in ligas and 4.

The spiral spring z. is made strong enough to counterbalance the weight of the blind nearly, so that when the blind is opened or closed, a very slight etl'ort will raise the blind and lift the pin t' out of the hole in the lower disk c, allowing the blind then to be moved readily either way, and its position changed.

`Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a blind-hinge, I claim the combination of the upper disk a, having the pintle la set in the socket d, the pin z'set in r`the holes'on the lower hinge, the catch-pin e in the pintle of the upper hinge, and the spiral spring z, all arranged and operating asf-.and for the purposes herein described.-

The -above speciiication of my invention signed by me this 20th day of November, 1866.
